PRODUCTION CARD CLOTHING Filed Sept. 27, 1933 2 Sheets-Sheet 2 lalyzw rok hTTORNEY Patented Feb.26, 1935 UNITED STATES PATENT OFFICE PRODUCTION OF CARD CLOTHING Application September 27, 1933, Serial No. 691,251 In Japan November 30, 1932 5 Claims.

The invention relates to the making of card clothing and has for its object to remove grinding dust and foreign matter from the work and thus obtain a clean appearance.

The invention is characterized in that a strip of paper or like thin flexible material is supplied on the point side of the card clothing at the wireinserting position, where the wires are inserted through both the foundation and the paper or the like, the said paper or the like being removed after the wire-inserting and subsequent grinding operations have been completed.

The accompanying drawings show one embodiment of apparatus for carrying out the invention.

Fig. 1 being a front view of, the apparatus; and

Fig. 2 a side view.

Referring to the drawings, 1 represents a roll of paper or the like, 2 a shaft on which the foundation 6 of the card clothing is rolled, and 3, 4 a pair of feed rollers. The paper strip 5 and the foundation 6 are supplied through the feed rollers 3, 4, to the same side of a guide rod '7, as shown in the drawings. In the inserting position above the guide rod '7 the wires 8 are inserted through both the foundation and the paper or the like in the usual or any preferred manner (not shown), so that the latter is secured on the point side of the card clothing. r

The card clothing after having been thus set is passed around a felt roll 10 and a guide rod or roller 11 to a shaft 12 to be wound on the latter. After the tips and sides of the teeth have been ground in the normal way, the paper or the like is removed and the card clothing is then complete.

In the known method dirt gets on to the card clothing during the making of the same and especially is the clothing spoiled by grinding dust getting into it during the grinding operation. According to the invention, however, the paper or like material is applied on the point side of the clothing before the wire-inserting operation and is closely secured by the wires or teeth to be retained in position during the grinding operation,

after which the paper or like material is torn or pulled off, and removes with it any dust or dirt which may be present between the teeth. Both the foundation and the teeth of the clothing are thus presented perfectly clean in the finished article. 1

Having thus described my invention, what I claim as new and desire to secure by Letters Pat ent is:

1. Card clothing having on its point side and at the base of the teeth a strip of thin flexible material.

2. The method of making a card clothing which includes the step of sustaining a protective covering against the point side of the card backing, and projecting the card teeth through said backing and protective covering from the other side whereby to provide a protective covering for the point side of the card backing.

3. The method of making a card clothing which includes the step of sustaining a protective covering against the point side of the card backing, and projecting the card teeth through said backing and protective covering from the other side whereby to provide a protective covering for the point side of the card backing, then grinding the card teeth, and finally removing the protective covering so as to leave the point side of the card clothing free of grindings and other foreign matter.

4. The method of making a card clothing which includes the step of juxtapositioning a flexible protective covering on one surface of the card foundation and inserting the teeth through both foundation and covering from the other side.

5. The method of making a card clothing which includes the step of assembling a protective covering against the surface of thecard foundation at the point side.
